Title: Combined mirror and shutter for SLR camera - is inclined at 45 degrees but parts in centre for coiling during exposure
Inventor: SCHWEIKERT ERNST
IPC: G03B19/12
Filed: 1977-08-17
Abstract: A flexible 45 deg. mirror unit for a s.l.r. camera also doubles as the shutter component. The foil mirror with a mass of approx. 300grms per sq metre is inclined at 45 deg. for viewing and it parts in the centre and is drawn and coiled to each side, still in the 45 deg. inclination, for exposure. This reduces exposure vibration since there is no heavy, pivoted mirror to swing upwards and be arrested. There is also a reduction in noise, wt., and size.

Title: Double heater unit for domestic linen dryer - uses only one programme for circuit controlled by two thermostats
Inventor: BOECKER HEINRICH
IPC: D06F58/50
Filed: 1979-02-05
Abstract: The sum, 2700W, of the effective loads of two heaters, of which the rating of the one is 1800W whilst that of the other is 900W, is such, that when the domestic linen dryer to which they are fitted, has a maximal filling of items with an average residual humidity of 75%, a bottom limiting temp. of 45 degrees C is reached. The 1800W heater is switched off by a thermostat at 60 degrees C, below the permitted max. for the most sensitive articles. It is switched back on again at 40 degrees C which is below the temp. reached by the 900W heater. The output of this latter is determined so that at a maximal filling of items of linen with a residual humidity of 5%, a temp. of is approx. 45 degrees C is maintained. This is so low that damage to the linen is avoided with certainty. The 900W heater is switched off by thermostat the energising temp. of which is 65 degrees C which is still below the permissible maximum but is however 5K above the switching-off temp. of the first thermostat. The second thermostat switches back on at 40 degrees C which is also below the temp. achieved by its 900W heater. The arrangement ensures that batches of linen of any type and quantity with practically any degree of humidity whatever, are dried in a manner which is specifically adapted to their individual case.
